This paper discussed the keystone species and introduced the typical characteristics of keystone species and their identification in communities or ecosystems. Based on the research of the keystone species, the concept of species importance (SI) was first advanced in this paper. The species importance...
The keystone-species concept in ecology and conservation. Argues that the term `keystone species' is broadly applied, poorly defined, and nonspecific in meaning. Furthermore, the type of community structure implie... Mills,L Scott,Soule,... - 《Bioscience》 被引量: 1191发表: 1993年 Centrality...

What Are Keystone Species? - Definition & Examples from Chapter 16 / Lesson 9 156 Keystone species are organisms that other species in the ecosystem depend upon and whose disappearance would devastate their biological communities. Learn how to define keystone species and review examples of why th...
Paine changed the field of ecology2. He experimentally removed starfish in study plots of 8 metres by 2 metres, observed the cascading ecological effects and then repeated the procedure. This work led to the keystone species concept3, suggesting that some species are more important than others ...
Fig. 1: Across the United States, distributions of Host Plant-Lepidoptera interactions are skewed such that few plant genera support the majority of Lepidoptera species. a White-blotched Heterocampa (Heterocampa umbrata) a Lepidopteran from the family Notodontidae. The majority of Lepidopteran cate...
Forests are essential for maintaining species diversity, stabilizing local and global climate, and providing ecosystem services. Exploring the impact of paleogeographic events and climate change on the genetic structure and distribution dynamics of fores
The Fagaceae family comprises about 1,000 woody species worldwide. About half belong to the Quercus family. These oaks are often a source of raw material for biomass wood and fiber. Pedunculate and sessile oaks, are among the most important deciduous for
Furthermore, the type of community structure implied by the keystone-species concept is largely undemonstrated in nature. Ambiguities and uncertainties; The implications of the keystone-species concept for ecology and conservation; The varied meanings of the term `keystone species'; Useful contributions...
A central issue in ecology is the definition and identification of keystone species, i.e. species that are relatively more important than others for maintaining community structure and ecosystem functioning. Network theory has been pointed out as a robust theoretical framework to enhance the operation...
